Our calcium aluminates are engineered to be a cost effective approach to fluorspar-free ladle slag fluxing. As many aluminum killed steel shops are restricted in the use of fluorspar, calcium aluminate consumption has increased as a means of fluidizing CaO in a quick and effective manner. Our extensive line of calcium aluminate products offers a wide range of capabilities to balance ladle slag chemistries while providing the basicity and fluidity required for effective steel refining in the ladle. Calcium aluminates also help to dilute the overall FeO and MnO levels in the carryover slag.
Calcium aluminates are sized in granular (-3/8”), coarse (+3/8 x 2”) and briquettes (2” x 1½” x ¾”). The granular material is typically supplied in 50 pound bags, 2,400 pounds per pallet. Custom bag sizes are also available. Our coarse calcium aluminates are supplied in supersacks; specific weights are designed for each application. Calcium aluminates are supplied in bulk, bins and supersacks. The vast majority are provided in bulk. All packaged calcium aluminates are supplied on sturdy pallets, shrink wrapped to protect from the environment.
Providing hands on technical support with complete ladle practice analysis utilizing our in-house metallurgical engineering staff, we have experienced steel industry sales personnel who work in conjunction with the highest professional manufacturer’s representatives. We also offer custom product design based on existing parameters such as furnace slag chemistry, slag carryover, alloys used and end point slag chemistry targets. We utilize our own in-house designed Mass Balance computer model. We offer practice recommendations and improvements for calcium aluminate additions. The process begins with a Slag Analysis of a customer’s current slag, proceeding to on site observations of practices and procedures, then during trials we take samples and evaluate the current slag practice, finally making recommendations to products and practices.
Analytical Capabilities & Quality
We test all incoming calcium aluminate raw materials, especially the levels of Al2O3, CaO, MgO, FeO, MnO and Sulfur. We also have the capability to test: metallic aluminum via hydrogen evolution, fluorine analysis via ion probe or XRF (X-Ray Fluorescence), full oxide analysis via XRF spectrometer, sulfur and carbon determination via LECO analysis, moisture and L.O.I. determination via high temperature furnace tests, tumble, crush, drop tests for physical strength of briquetted products, bulk density, specific gravity, sizing determinations and mineralogical and metal determinations via XRD (X-Ray Diffraction). Our facilities are ISO 9001; 2008 certified.
Each production facility contains: bulk silo storage of raw materials, rotary dryer with attached screening, bulk blending and packaging, two briquetting lines with attached screening, warehouse space for finished products and lab facilities for material testing. We offer dual plant capabilities, custom blending and packaging, superior on time delivery, utilizing the highest quality raw materials, striving to exceed customer requirements.
